При переносе/копировании VM создается новый MAC-адрес у сетевухи. [more]...for every vNIC that gets created and assigned
to a virtual machine, a unique MAC address is created. This MAC
address gets stored in the VMX file for the virtual machine in which
it is created. VMware utilizes several mechanisms when verifying the
uniqueness of the MAC addresses that are assigned. The first, and
most obvious, mechanism is the use of unique 3 bytes
Organizationally Unique Identifiers (OUIs). These OUIs ensure a
VMware vNIC receives a MAC address that is completely unique
from any other network card vendor. VMware has the following
OUIs registered:
00:0c:29
00:50:56
00:05:69
Unless you have machines that have been upgraded from ESX 1.5,
there is a good chance that you will not see the 00:05:69 OUI in use
on any virtual machines.
The second mechanism for ensuring each vNIC receives a unique
MAC address is by utilizing the UUID of the virtual machine. Each
virtual machine has a unique UUID number that is based on several
factors. An algorithm is calculated against this UUID and the remaining
3 bytes of the MAC address are generated. Even when utilizing
this algorithm, VMware cannot guarantee the uniqueness of the MAC
address. To combat a MAC address conflict scenario, ESX performs
an integrity check and if a conflict is detected, a new MAC is generated.
ESX performs integrity checks until a unique MAC address is
generated. Once generated, the MAC address is written to the VMX
file of the virtual machine the vNIC is configured for and will not
change unless the path to the VMX file for the virtual machine
changes.[/more]
